I disagree, kit beast isn't too op at all. even a wizard kit can kill anyone with a beast kit. It's mostly about how good you are.
(late to this but) It's not that hard to kill a beast kit if you know the right tactic and are smart. I'm sure they put a lot of consideration into what kit gets what. If they were perfectly even there would be no point of kits, and it would be less fun. Overall I'm going to deem this suggestion not valid...The beast kit can tank almost anything, as well as having an okay weapon. Archers are useless against it, as it takes so many arrows to kill. I would suggest a slowness debuff, or maybe a weaker weapon.
